SMOKING-TUBE.

SPECIFICATION forming part of Letters Patent No. 561,288, dated June 2, 1.896.

Application filed March l, 1895. Serial No. 540,191. (No model.)

To all whom, t may con/cern:

Be it known that I, Lewis H. SoNDHn1M,of

Y New York, in the county and State of New York, have invented new and useful Improvements in Smoking Tubes and Pipes, of which the following is a full, clear, and exact description.

The invention relates to that class of smoking-tubes in which the tobacco is fed to the front of the tube as fast as it is consumed; and the object of the invention is to improve smoking devices of this character in several particulars, as will be explain ed hereinafter.

The invention consists in the novel features hereinafter particularly described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts in all the views.

Figure lis a longitudinal sectional view of a smoking-tube constructed in accordance with my invention. Fig. 2 is a similar view, but representing the piston or follower in a more forward position. Fig. 3 is a cross-section on the line 3 in Fig. 2. Fig. et is a cross-section on the line a i in Fig. 2. Fig. 5 is a perspective view of the cartridge-shell of the smoking-tube. Fig. 6 is a broken perspective view of the combined piston and stem of the smoking-tube. Fig. 7 is a longitudinal sectional View of a modified form of cartridgeshell. Fig. S is a broken longitudinal section showing a further modification of the cartridge-shell.

The smoking-tube A, of wood or other material, is provided at its front end with a bushing B, of incombustible material, the bushing having a flange b, that overlaps and protects the front edge of the tube A, and the bore of the bushing further is preferably contracted at its forward end, as at b.

Vithin the tube A is a cartridge-shell C, to be hereinafter more particularly referred to, the shell serving to receive the tobacco o. In connection with the cartridge a piston D is employed having a head or follower D and a pusher-stem D2. Said stem extends to the outside of the tube A, through the plug or cork E, and it has an axial bore d, through which the smoke is finally drawn, as explained below, the outer end d of the stem being the mouthpiece of the tube and finished in practice in any approved manner.

The shell C is of sufficiently less external diameter than the bore of tube A to provide a chamber or passage a, and the stem D2 is of sufficiently less diameter than the bore of the shell C to provide a chamber or passage a2 between the two when the stem is partly within said shell, as in Fig. 2.

A suitable opening h2is formed in the bushing I3 to connect the combustion-chamber formed by such bushing with the forward end of the outer chamber a, and the inner and outer chambers a' o2 communicate by reason of openings a3 in the rear end of the shell C, and the inner chamber c2 communicates with the axial bore d of the stein D by transverse openings or branch passages d2 in said stem. In connection with the head D there is provided at a point between the head D and the openings d2 a packing-ring d3, which is somewhat larger in diameter than the bore of the shell C and is flexible to incline rearwardly, as in full lines, or forwardly, as in dotted lines, Fig. 2, according to the direction of movement of the piston, and it effectively prevents smoke working forwardly past the same Or the drawing' of smoke rearwardly through the bulk of the tobacco and past the packing. Thereby the bulk of the tobacco is preserved from contamination'.

The rear plug or cork E is reduced at its forward end to provide a shoulder 6 which abuts the rear end of the tube A, the reduced projecting end e fitting tightly within said tube, and in the bore of the cork a packingring e2 is held to tightly fit on the stem D2 and prevent ingress of air, the packing-ring e2 being held in place by the two bushingrings e3, one at each side of said packing-ring or in any other suitable manner.

The shell C is shown in Figs. l, 2, and 5 as of a form to abut against the rear edge of the bushing` B, and in one piece. In Fig. 8 the forward end of the shell C3 enters slightly within the bushing B', forming the combustion-chamber, the said bushing having its bore enlarged at the rear to receive the shell and has an internal shoulder b3, against which the shell abuts.

In Fig. 7 the forward end of the shell C2 is received within a cap-piece C', which is of IOO glass, metal, or other incombustible material, the forward end of said cap being contracted to provide a bore corresponding to that of the shell proper; but whether the shell fits within the cap-piece or the reverse is of no moment. The cap-piece C may abut the bushing I3 or may be reduced, as shown at h4, to fit the enlarged rear end of a bushing B, Fig. 8, and abut the shoulder b3, an orifice c being preferably formed in the cap-piece or end piece C for the smoke,the said orifice being a substitute for or additional to the opening b2. In Fig. 8 also the shell is shown with an opening c at its forward end for the outward passage of the smoke to the chamber a. Thus it will be seen such outlet may be in the shell or in the bushing I3 or B or in both the shell and bushing.

The shell may be made of metal, glass, wood, paper, or paper or wood pulp; but my preferred forni is paper, paper-board, or like brous material, and such fibrous shell is glazed internally and also, preferably, externally. Theinterior glazingprovides a smooth surface which facilitates the forward movement of the tobacco, and the exterior glazing lends an attractive appearance to the cartridge. Further, the shell is given stiffness sufficient to withstand endwise strain without being crumpled or crushed.

In practice the cartridge-shells are designed to be sold filled ready for insertion in the tube, and in use the plug E or E is removed, the cartridge is inserted in the tube A, the piston-head D is pushed into the rear end of the cartridge, and the plug E or E', with the stem D2 passing therethrough, is replaced in the tube. The entering of the piston-head D will have filled the combustion-chamber and the tobacco is ready to be lighted. As fast as the tobacco is consumed at the forward end of the tube the remainder is successively advanced by pushing the piston forward. The smoke is drawn from the combustion-chamber into the chamber a', along the latter to the rear end of the shell, thence through the apertures a3 to the inner chamber or passage ce2, forwardly in the passage a2 to the lateral openings d2 of stem D2, and, finally, rearwardly through said stem.

It will be observed that the cartridge has a bore without inwardly-projecting shoulders, and that the tobacco is not consumed therein, but is gradually ej ected,to be consumed therebeyond, and this feature, as well as the endwise stiffness of the shell and also theglazing of the shell, are distinguishing characteristics of my invention, the cartridges thus formed and filled with tobacco being designed for sale as an article of commerce, to be purchased by those possessing my improved smokingtube, the shell to be removed and discarded after the tobacco vis consumed. The shell may, however, be refilled.

By glazed paper I refer to the papers which are sufficiently coated or sized and iinished to provide a pronounced smooth surface,

this usually being effected by manufacturers by applying a sizing or clayey coating to the surface and finishing by calendering, and I wish to be understood as employing the term glazed paper in its broader meaning and including what is technically known as coated papers, as well as that technically known as glazed.

The packing-washer or the like, it will be understood, is actually a coacting part of the follower, the two being on the manually-operated stem and serving to push forward the tobacco from the outside, while preventing entrance of smoke in either direction to the unconsumed body of the tobacco.

The extreme ond of the head D has a tip D3 of refractory material.

It is preferred to make the head of the piston-stem imperforate and so tight as to prevent of itself the passage of the smoke; but it will be apparent that as the smoke may pass very freely from the combustion-chamber thro ugh the exterior passages to the stem, it will not be drawn in any material amount through the mass of the tobacco, which is packed more or less tightly initially and by the pressure of the piston-head, even should the said head be constructed so as not of itself to form a positive bar to the passage of the smoke. My invention is therefore not limited to an imperforate or tightly-fitting head.

Having thus described my invention, I claim as new and desire to secure by Lett-ers Patent l. A smoking device having a central chamber for receiving the tobacco, the forward end of the smoking device forming a combustionchamber, said device further having a smokepassage exterior of the tobacco-chamber, and a longitudinally-movable stem adapted to be manually operated and fitting into the tobacco-chamber, and having an axial bore in communication with said exterior smoke-passage, substantially as described.
